“The faces of the delegates are difficult to see, but the painting features a clear image of a jougwan,” a museum press release said. A jougwan is a hat that was worn by the men of Goguryeo and was decorated with a bird’s feather. The mural, along with other relics of the era, are part of the exhibit The Crossroads of Civilizations: The Asian Culture of Uzbekistan, which demonstrates the country's importance as a stop along the Silk Road.
